Locks

NDC provides information on locks through the Lock Performance Monitoring System (LPMS), which is a web-based system used to collect and report data on vessels that traverse through Corps-owned or operated locks in near real-time. The primary purpose of the LPMS is to capture data relating to operations of locks, which acts as a planning tool for vessel operators and aids them in tracking progress of goods shipped on U.S. waterways. This information is then posted on Corps Locks.

Lock Performance Monitoring System (LPMS)

The LPMS is a web-based system that is used to collect and report data on vessels as they traverse through Corps-owned or operated locks. Data on vessel movements, location, lockage times, and delays is entered either manually or by lock operators or via automatic identification systems (AIS) from ships. Reporting information from the LPMS is summarized in Corps Locks. (link is to info-graphic only)
